An outgoing call and an advertisement service operation of an advertisement and security monitoring service system using an IP-based branch exchange (IP-PBX) having such a configuration will be described in detail with reference to FIGS. 4A and 4B. .

First, when a telephone user belonging to an arbitrary PC client 30 wants to make a predetermined outgoing call, the VoIP processing unit 31 activates the IP phone controller and reports to the application processing unit 34 that the IP phone controller has been activated. In this case, the application processing unit 34 provides a series of advertisement services for displaying advertisement data stored in the advertisement data DB on the PC screen (step S11).

Then, the VoIP processing unit 31 of the calling PC client 30 starts the IP phone controller and simultaneously requests the public telephone number to the IP-PBX gateway server 20 through the LAN to the IP-PBX gateway server 20. After receiving the list of public phone numbers stored in the phone number DB from the VoIP processing unit 21 of the displayed on the PC screen with a list of personal phone numbers stored in the phone number DB that he manages, The telephone user of the calling PC client 30 operates the keypad of the telephone to enter a party's number (PC extension number, external public telephone number, external VoIP number, etc.), or the public telephone number displayed on the PC screen and the internal. When a desired counterpart number is selected from the list of personal phone numbers, the counterpart number is transmitted to the IP-PBX gateway server 20 through the LAN to send an outgoing request. It is (Step S12).

At this time, the IP-PBX gateway server 20 analyzes the party number received when the PC client 30 makes a call request and checks whether the call request is for an extension call or a call request for a trunk line call (step S13). ).

When the IP-PBX gateway server 20 analyzes the counterpart number, and it is determined that the call is an outgoing request requesting an extension call, the VoIP processing unit 21 searches the phone number DB and the counterpart number received in the outgoing request. After detecting the IP address of the PC client 30 assigned to the same extension number, that is, the receiving PC client 30 (step S14), it is checked whether the receiving PC client 30 is currently available for call ( Step S15), if it is determined that the call is in a non-call state (for example, in a call or a disconnect state, etc.), the PC client 30 requesting to send a message including the corresponding non-call state information, that is, the calling PC client 30 ), The originating call process is terminated (step S16).

However, if it is determined that the PC client 30 assigned to the same extension number as the counterpart number, that is, the receiving PC client 30 is currently in a callable state, the VoIP processing unit 21 of the IP-PBX gateway server 20 The IP address of the receiving PC client 30 detected above is transmitted to the calling PC client 30, and the advertisement data stored in the advertisement data DB is reported to the application processor 24 by reporting that the outgoing call is being processed. Is transmitted to the calling PC client 30 via the LAN (step S17).

Then, the VoIP processing unit 31 of the calling PC client 30 receiving the IP address of the receiving PC client 30 transmits a call request signal directly to the IP address of the receiving PC client 30 through the LAN. (Step S18), and when the receiving side PC client 30 responds to the call request, an extension call is performed. At this time, the application processing unit 34 transmits the advertisement transmitted from the IP-PBX gateway server 20. When the data is stored and managed in the advertisement data DB, and the receiving PC client 30 provides the extension call service in response to the call request, the VoIP processing unit 31 stops the advertisement service using the existing advertisement data. By linking, it will provide a series of advertisement services that display advertisement data newly stored in advertisement data DB on PC screen. In addition, when the receiving PC client 30 recognizes a call request from the calling PC client 30, the VoIP processing unit 31 activates the IP phone controller to transmit a ring signal to the telephone. In response, the call client of the calling PC client 30 is provided with an extension call service. At this time, in conjunction with the application processor 34, a series of advertisement data stored in the internal advertisement data DB is displayed on the PC screen. The advertisement service is provided (step S19).

On the other hand, in step S13, the IP-PBX gateway server 20 checks the status of the internal VoIP processing unit 21 when it is determined that the call request is for the trunk line call as a result of analyzing the counterpart number. It is checked whether there is a possible VoIP processing unit 21 (step S20), and if it is determined that there is no VoIP processing unit 21 capable of trunk line call, corresponding call impossible status information (eg, a CO line connected to all VoIP processing units). After the message including the busy or unreachable state is transmitted to the originating PC client 30, that is, the originating PC client 30, the originating call processing is terminated (step S21).

However, if it is confirmed that the VoIP processing unit 21 capable of trunk line call exists, the IP-PBX gateway server 20 transmits the IP address assigned to the VoIP processing unit 21 to the calling PC client 30. In this case, the VoIP processing unit 21 transmits the call request signal by converting the other party's number received in the outgoing request according to a series of outgoing call processing procedures into DTMF signal form and transmitting it to the receiving side exchange through the trunk line connected to it. Further, by reporting that the originating call is being processed to the application processing unit 24, the advertisement data stored in the advertisement data DB is transmitted to the calling PC client 30 via the LAN (step S22).
